Procedure of a medical store license in India?

Hi,
I owe a degree in B.Pharma and i was planning to open a medical store of my own but the problem is that i heard it from my friend that if you wish to open a medical store then first you have to get a license from Indian government and after getting it then you can open it up it is not so easy. So i was reseraching it but unable to find it where to apply and where to get it from. So, anyone have information regarding my query then please make it available for me as soon as possible.

thankyou,
